Technical Field

[0001] The utility model relates to the technical field of filter barrels, in particular to a structure of a pulp fiber filter barrel. Background Art

[0002] Pulp is a fibrous substance made from plant fibers by different processing methods. Pulp is processed from certain plants and is the basic raw material for papermaking. The plants usually used as pulp raw materials can be divided into four categories: stem fiber category, bast fiber category, seed hair fiber category, and wood fiber category. Among them, the wood fiber category is the most important. In the existing papermaking technology, in order to improve the quality of paper, a filter barrel is often used to filter the group fibers and impurities in the pulp to ensure that the pulp is fine enough.

[0003] In the use process of the existing fiber filter barrel, the pulp is mainly introduced into the interior of the filter barrel, and then the rotation of the filter barrel is used to make the coarse fibers and impurities in the pulp stay in the filter barrel, and the finer pulp is filtered and discharged. During this process, since the coarse fibers and impurities in the pulp will form fiber clusters due to the rotation of the filter barrel, and some finer pulp will be wrapped in the fiber clusters and it is difficult to separate from the coarse fibers, resulting in waste of pulp. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing filter barrel, the utility model provides a structure of a pulp fiber filter barrel, which has the advantages of being able to break up the coarse fiber clusters in the filter barrel, using water flow to wash the broken-up fiber clusters, and reducing pulp waste, and solves the technical problems such as some fine pulp being wrapped by fiber clusters.

[0005] The utility model provides the following technical solution: A structure of a pulp fiber filter barrel includes a bottom plate, and further includes:

[0006] A fixing plate, fixedly installed on the left side of the top surface of the bottom plate. A pulp inlet pipe is fixedly installed in the middle of the fixing plate. The front side of the right part of the top surface of the bottom plate is fixedly connected with a support frame. A rotating shaft is rotatably sleeved in the middle of the support frame. A gear is fixedly sleeved in the middle of the rotating shaft. A motor is fixedly installed at the left end of the rotating shaft.

[0007] A fixing frame, fixedly connected to the front side of the left part of the top surface of the bottom plate. A movable shaft is fixedly sleeved in the middle of the fixing frame. A support wheel is rotatably sleeved in the middle of the movable shaft. A filter barrel is placed on the support wheel. A transmission tooth is fixedly connected to the outer surface of the right part of the filter barrel. The transmission tooth is in transmission engagement with the gear. Filter holes are formed in the side wall of the filter barrel.

[0008] Preferably, the pulp inlet pipe includes:

[0009] The support plate is fixedly connected to the inner side wall of the pulp inlet pipe;

[0010] The connecting rod is fixedly connected to the middle of the side surface of the support plate facing the inner cavity of the filter barrel.

[0011] Preferably, the connecting rod includes:

[0012] The fixing rod is fixedly connected to the outer surface of the connecting rod;

[0013] The spiral strip is fixedly connected to one end of the fixing rod away from the connecting rod, and the spiral strip contacts the inner side wall of the filter barrel.

[0014] Preferably, the connecting rod includes:

[0015] The cavity is opened inside the connecting rod;

[0016] The water outlet hole is opened on the side wall of the connecting rod, and the water outlet hole communicates the cavity with the inner cavity of the filter barrel;

[0017] The water pipe is fixedly connected to the middle of the right end face of the connecting rod, and the water pipe communicates with the cavity.

[0018] Preferably, the connecting rod further includes:

[0019] The inclined plate is fixedly connected to the lower side of the connecting rod and is located at the outer surface of the fixing rod in the vertical direction. The inclined plate is located directly below the water outlet hole.

[0020] Compared with the prior art, the present utility model has the following beneficial effects:

[0021] 1. By designing the support plate, connecting rod, fixing rod, spiral strip, etc., when the filter barrel filters the pulp, since the filter barrel is always in a rotating state, and the connecting rod is fixed to the pulp inlet pipe through the support plate, but the pulp inlet pipe is in a static state, so relative movement will be formed between the fixing rod and the spiral strip and the filter barrel, making the fiber mass inside the filter barrel be dispersed by the spiral strip, avoiding some delicate pulp being wrapped by the fiber mass.

[0022] 2. By designing the cavity, water outlet hole, water pipe, etc., water flow is introduced into the cavity through the water pipe, and then the water flow will be discharged through the water outlet hole after entering the cavity, making the water flow impact on the inner side wall of the filter barrel. Since the fiber mass in the filter barrel has been dispersed by the spiral strip at this time, when the water flow impacts the dispersed fiber mass, the delicate pulp in the fiber mass will be washed away by the water flow, reducing the waste of pulp.

[0023] 3. By designing the inclined plate and cooperating with the rotating filter barrel and the spiral strip, the fibers filtered out in the filter barrel will be lifted by the spiral strip. Then, some of the lifted fibers will fall on the inclined plate. After the water flow in the cavity is discharged through the water outlet holes, it will also impact on the inclined plate, enabling the thick fibers on the inclined plate to be washed by the water flow as much as possible, so as to wash out the delicate pulp in the thick fibers and further improve the utilization rate of the pulp.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 4, a structure of a pulp fiber filter cartridge, comprising a bottom plate 1. On the left side of the top surface of the bottom plate 1, a fixed plate 2 is fixedly installed. In the middle of the fixed plate 2, a pulp inlet pipe 3 is fixedly installed. On the front side of the right part of the top surface of the bottom plate 1, a support frame 4 is fixedly welded. In the middle of the support frame 4, a rotating shaft 5 is rotatably sleeved. In the middle of the rotating shaft 5, a gear 6 is fixedly sleeved. At the left end of the rotating shaft 5, a motor 7 is fixedly installed. The output end of the motor 7 is fixedly welded to the rotating shaft 5. On the front side of the left part of the top surface of the bottom plate 1, a fixed frame 8 is fixedly welded. In the middle of the fixed frame 8, a movable shaft 9 is fixedly sleeved. In the middle of the movable shaft 9, a support wheel 10 is rotatably sleeved. A filter cartridge 11 is placed on the support wheel 10. On the outer surface of the right part of the filter cartridge 11, a transmission tooth 12 is fixedly welded. The transmission tooth 12 is in transmission engagement with the gear 6. Filter holes 13 are formed on the side wall of the filter cartridge 11.

[0031] Please refer to Figures 1 - 4 , on the inner side wall of the pulp inlet pipe 3, a support plate 31 is fixedly welded. In the middle of the side surface of the support plate 31 facing the inner cavity of the filter cartridge 11, a connecting rod 32 is fixedly welded, ensuring that the connecting rod 32 can be fixed on the inner side wall of the pulp inlet pipe 3 through the support plate 31, so that the connecting rod 32 remains stationary like the pulp inlet pipe 3.

[0032] Please refer to Figures 1 - 4 , on the outer surface of the connecting rod 32, a fixed rod 33 is fixedly welded. At the end of the fixed rod 33 far from the connecting rod 32, a spiral strip 34 is fixedly welded. The spiral strip 34 is in contact with the inner side wall of the filter cartridge 11, ensuring that the spiral strip 34 remains stationary while the filter cartridge 11 rotates, so that a relative movement is formed between the filter cartridge 11 and the spiral strip 34, and the spiral strip 34 will disperse the fiber mass in the filter cartridge 11 to prevent the fiber mass from wrapping some delicate pulp inside.

[0033] Please refer to Figures 1 - 4 , a cavity 35 is formed inside the connecting rod 32. Water outlet holes 36 are formed on the side wall of the connecting rod 32. The water outlet holes 36 communicate the cavity 35 with the inner cavity of the filter cartridge 11. In the middle of the right end surface of the connecting rod 32, a water pipe 37 is fixedly welded. The water pipe 37 communicates with the cavity 35, ensuring that water can enter the cavity 35 through the water pipe 37 and finally discharge through the water outlet holes 36, so as to wash the dispersed fiber mass, and the delicate pulp doped in the fiber mass will be washed out by the water flow.

[0034] Please refer to Figures 1 - 4 , on the outer surface of the fixed rod 33 located vertically below the connecting rod 32, an inclined plate 38 is fixedly welded. The inclined plate 38 is located directly below the water outlet holes 36, ensuring that some of the fiber mass will be brought to the inclined plate 38 by the spiral strip 34 after being dispersed, and the water outlet holes 36 will directly wash the thick fiber on the inclined plate 38, ensuring that the delicate pulp doped in the thick fiber will be washed by the water flow and reducing pulp waste.

[0035] Working principle: When the pulping fibers need to be filtered, the pulp is introduced into the filter barrel 11 through the feed pipe 3. Then, the motor 7 is started, and the motor 7 drives the rotating shaft 5 and the gear 6 to rotate. The gear 6 meshes with the driving teeth 12 and drives the filter barrel 11 to rotate. After that, the filter barrel 11 is supported by the support wheels 10, so that the filter barrel 11 filters the pulping fibers during rotation. During this process, since the filter barrel 11 is always in a rotating state, while the connecting rod 32 is fixed to the feed pipe 3 through the support plate 31, but the feed pipe 3 is in a stationary state, relative movement will be formed between the fixing rod 33 and the spiral strip 34 and the filter barrel 11, so that the fiber mass inside the filter barrel 11 will be dispersed by the spiral strip 34, avoiding some delicate pulp being wrapped by the fiber mass. At the same time, water flow is introduced into the cavity 35 through the water pipe 37, and then the water flow will be discharged through the water outlet holes 36 after entering the cavity 35, so that the water flow will impact on the inner side wall of the filter barrel 11. Since the fiber mass in the filter barrel 11 has been dispersed by the spiral strip 34 at this time, when the water flow impacts the dispersed fiber mass, the delicate pulp in the fiber mass will be washed away by the water flow, reducing the waste of pulp. Secondly, through the cooperation of the rotation of the filter barrel 11 and the spiral strip 34, the fibers filtered out in the filter barrel 11 will be lifted by the spiral strip 34, and then some of the lifted fibers will fall on the inclined plate 38. After the water flow in the cavity 35 is discharged through the water outlet holes 36, it will also impact on the inclined plate 38, so that the coarse fibers on the inclined plate 38 can be washed by the water flow as much as possible, thereby flushing out the delicate pulp in the coarse fibers and further improving the utilization rate of the pulp.
